To all whom itmoy concern Be it known that Hnnrrarr'H. F sorrnn, acitizen ofthe United States, and aresident of Lebanon, in the county ofTJelianon-and State of Penneyll rania, have-invented a new and Improvedire-Rim T001 of which the following is a full, clear, and eimctdescription. 7 l

The-inventionrelates to appliances for removin a splitde'meuntable-rimfrom atire or rep aciiig the rim onJthe' tire.

The object .ofthe invention is to rovide a new and improved tirerim'tool w ich is simple and durable in construction, easily placed inposition and arranged to require comparatively little physical exertionon the part of the user to successfully manipulate the tool.

Another object is to provide a rim tool which is exceedinfily compacttakes up little roam, and is not iable to get easily out of or er.

Another obj act the use of the rim somewhat in diameter; With theseandother objects in :view, the invention consists of certain novel.features of construction as hereinafter showninnd described and'thenspecifically pointed-out in the claims,

ada- Jted to hook onto one of the flanges 20 oft e usual split rim 21-adapted to carry a tire 22; i

It' is understood that the hook .17 engages the flange 20 of the rim 21adjacent one end thereof while the other hock 18 engages the flange 20approximately diametrically oppoeite the portion engaged b the hook 17,as will be readily und'ersboo liy reference to Fig.'-1. When the hooks1'7 and 18 are-in engagement with the flange 20' of the rim. 2-1was-described, and the-turnbuclde'ltl is turned with a view tomovethe-'tnmbuckle rods 13 and 14 toward eachother then the split end a ofthe rim 21 is moved inward to contract the rim to allow convenientremoval of the tire 22 from the rim or replacing of the tire on the rimas the case may be.

In order to equalize the pull of the turnbuckle rods 13 and 14 on therim 21, use is made of equalizing members 25 and 26 in the form ofplates mounted to swing on the shanks 27 and 28 of the hooksli and 18.The equalizing members 25 and 26 are adapted to fit between the innerface of the rim 21nd the angular arms 15 and 16, and the snidjequalizingmembers 25 and 26 extend with their free ends beyond the middle of theinnerfface of the rim 21 and hence the pull exertedby thetu'rnbuclclercds 13 and; 14 on moving the-latter toward each-other issame-time the'hoolrs 17 and 18 are securely locked-in place on theflange 20 0f the rim,

21. It will furthenbe noticedthet whenpthe turnbuckle 10'is turned inthe opposite dij faction-and the turnbuckllfi'ods 13 and-14 are, moved'from each other then the equal a to xpe d the same haclrato normalposition, th after the tire is pos'ition on-the Each equalizing member25, 26 has the outer'flflat' face fitting against theinner face of therim 21, while the inner face of the wedge-shaped member is rovided withtwo wed SOV a'nd 31' of d erent thicknesses oqmp'ensate for anydifierence in the dimeter'ofj the rim ;on which the is used at thetimefs'eeEi Aland 5).

: ='I hehooks 1 and 18 are. referably flattened =attheir ends toawidtexceedingthe diameters of; the shanks '27,?8'thus preventizingmemb'ers25and 26-act onthe rim some i' "and either of the some is adapted to.beseate'd .on-tlie corresponding. arm 15 0i '16 to ing the equalizingmembers and 26 from becoming accidentally disengaged from the hookshanks.

The tire rim toolshown and described 18 very simple and durable inconstruction and can be readily placed in position on the rim with aview to contract or expand the same as above explained.

It will further be noticed that by the use of the equalizing members 25and 26 n. straight pull is exerted on the spht ends of the rim thuspreventing the pulling of the rim out of shape when contracting thesame.

Having thus described my invention, I claim as new and desire to secureby Lettcrs Patent 1. In a tire rim tool, a turnbuckle having right andleft threads, tuinbuckle rods screwing at their inner ends in the saidturnbuckle, the outer ends of the turnbuckle rods having interal'angnlar arms terminating in hooks adapted to hook onto one of theflanges of an automobile wheel rim, and equalizing members mounted toswing on the shanks of said hooks in between the angular arms and theinner face of the rim.

2. In a tire rim tool, a turnbuckle having right and left threads,turnbuckle rods screw' at their inner ends in the said tnrnbuc le, theouter ends of the turnbuckle rods havin integral angular armsterminating in boots adapted to hook onto one of the flanges of anautomobile wheel rim, and an equalizing member mounted to swing on theshanks of the said hooks and in between the an ular arms and the innerface of the rim, each equalizing member having a flat face arla uted toengage the inner face of the rim, anclen-ch having two wedgeshnpedportions of different thickness forming the other face, either of thewedgeshaped portions being ada ted to be seated on the corresponding angar arm.
